Advanced Technology Materials Applied to Guideways, Highways and Airport Runways
This report summarizes the results of the research program which tested first five different types of ceramic material and later a second set in a small section of the test track of the Pennsylvania Pavement Research Facility, located at the University, accompanied by parallel laboratory testing. The materials in small slab or tile form were mounted on the concrete with a latex-modified mortar, additional latex-modified concrete was used to fill the remaining volume to the level of the pavement. The first set of materials have performed extremely well, essentially unchanged after passage of axle loads (846,000 18-Kip-equivalent axle loads) of a truck with full trailer (loading to correspond to maximum allowable in Pennsylvania). Periodic visual observations and measurements of skid resistance and wear indicated essentially zero change (regular groove patterns designed into three different materials allowed precise determination of amount of wear). Essentially no indication of cracking, failure or other deterioration of the materials was observed. More variability in performance of the second set of materials was observed, but most performed well up to 476,000 axle loads.
